What is the difference between resin bound and resin bonded surfacing?

Resin bound and resin bonded are different products. Resin bound: aggregate is mixed through the resin before application — creating a smooth, permeable, stable surface. Resin bonded (also called resin spray or scatter coat): resin is applied to the surface and aggregate is scattered on top — the result is more textured, not fully permeable, and looser aggregate can come free over time. Surface Master Australia installs resin bound (the premium, fully-encapsulated system) only.

Resin Bound Driveways vs Exposed Aggregate: Which is Better for Sydney Homes?

Honest comparison of resin bound driveways vs exposed aggregate for Sydney homeowners. Installation, drainage, lifespan, cost, UV stability, and pool safety compared.

Service benefits

Resin bound paving is permeable (water drains through the surface) while exposed aggregate concrete is impermeable — a key difference for Sydney stormwater management and pool safety.
UV-stable resin binders are essential for Sydney's high-UV climate — always confirm your contractor uses aliphatic polyurethane or equivalent UV-resistant resin chemistry.
Both systems are cost-competitive at $80–$180/sqm for residential Sydney driveways, with resin bound over an existing base being the most cost-efficient option.

Pricing and project context

Project context still depends on slab condition, surface size, preparation depth, finish selection, access, and cure timing; request a written quote for fixed pricing.

FAQs

Is resin bound paving permeable?

Yes. Resin bound paving is fully permeable — water drains through the aggregate matrix into the base below. This eliminates surface water pooling, reduces stormwater runoff, and is a significant safety advantage around pool areas. Exposed aggregate concrete, by contrast, is impermeable and requires adequate drainage falls.

How long does resin bound paving last in Sydney?

A quality resin bound installation using UV-stable polyurethane or aliphatic resin binders typically lasts 15-25 years in residential applications in Sydney. UV stability is critical — cheaper aromatic resin binders will yellow and degrade within 2-3 years in Sydney's high-UV environment. Always confirm the resin specification with your contractor.

Is resin bound paving suitable around swimming pools?

Yes — resin bound is one of the best surface choices for Sydney pool surrounds. Key advantages include: excellent slip resistance from the aggregate texture, permeable drainage that eliminates water pooling, a cooler underfoot temperature than concrete or dark pavers in summer, and chemical resistance to chlorine and pool chemicals.

Which driveway surface is better for Sydney's climate?

Both exposed aggregate and resin bound are suitable for Sydney's climate, but resin bound has key advantages in Sydney specifically: better management of summer stormwater runoff, cooler surface temperature in high UV conditions, and no requirement for periodic sealing. In coastal Sydney locations (salt air, high moisture), resin bound also performs well due to its UV-stable binders.
